CET ANNEAU EST SITUE DANS LA REGION DE LA TRANSITION ENTRE, D'UNE PART, UN ENTONNOIR DE PROTECTION EN SOUFFLET 1, ENTOURANT UNE ARTICULATION A FOURCHE 10 A UNE EXTREMITE DE L'ARBRE ARTICULE, D'AUTRE PART, UNE PIECE 9 RELIANT L'ENTONNOIR 1 A UN TUBE DE PROTECTION QUI ENTOURE UNE PARTIE DE L'ARBRE ET EST MONTE ROTATIF AUTOUR DE LUI 8.THIS DEVICE INCLUDES, AT EACH END OF THE ARTICULATED SHAFT, A REINFORCEMENT ELEMENT IN THE FORM OF A SUPPORT RING 6. THIS RING IS LOCATED IN THE TRANSITIONAL AREA BETWEEN, ON THE ONE HAND, A BELLOWS PROTECTION FUNNEL 1, SURROUNDING A FORK JOINT 10 AT AN END OF THE ARTICULATED SHAFT, ON THE OTHER HAND, A PART 9 CONNECTING THE FUNNEL 1 TO A PROTECTIVE TUBE THAT SURROUNDES A PART OF THE SHAFT AND IS MOUNTED ROTATING AROUND HIM 8.
Description
La présente invention se rapporte à un dispositif de protection pour unThe present invention relates to a protection device for a
arbre articulé servant à relier un tracteur à un appareil agricole porté, comportant deux tubes de protection pouvant coulisser l'un dans l'autre, entourant l'arbre articulé et comprenant chacun, à une extrémité de l'arbre articulé, une pièce d'appui de forme annulaire montée rotative dans une rainure annulaire de la tige d'une fourche d'articulation disposée à l'extrémité considérée de l'arbre articulé, une pièce de liaison articulated shaft used to connect a tractor to a mounted agricultural implement, comprising two protective tubes which can slide one inside the other, surrounding the articulated shaft and each comprising, at one end of the articulated shaft, a piece of annular support rotatably mounted in an annular groove of the rod of an articulation fork disposed at the considered end of the articulated shaft, a connecting piece

tection. Il est connu, par le brevet de la République Fédérale d'Allemagne DE-PS 26 09 069, d'appuyer l'un contre l'autre deux entonnoirs de protection, servant à recouvrir une articulation à grand angle et dont les côtés ouverts sont dirigés l'un vers l'autre, au moyen d'un anneau de soutien qui s'emboîte sur les deux entonnoirs. L'anneau de soutien décrit dans le document cité ci-dessus a toutefois l'inconvénient qu'il ne constitue pas un renfort à l'égard des forces radiales produites dans la zone de l'articulation. En cas de maniement non conforme, il peut donc en tection. It is known, by the patent of the Federal Republic of Germany DE-PS 26 09 069, to press one against the other two protective funnels, used to cover a joint at a wide angle and whose open sides are directed towards each other, by means of a support ring which fits on the two funnels. The support ring described in the document cited above has the disadvantage, however, that it does not constitute a reinforcement with respect to the radial forces produced in the area of the joint. In the event of improper handling, it can therefore
résulter des dommages pour le dispositif de protection. result from damage to the protective device.
L'invention a pour objet de créer un dispositif de protection qui constitue une protection efficace, sans limiter l'angle de flexion, et qui puisse également conserver son aptitude fonctionnelle sous des contraintes radiales et axiales élevées, The object of the invention is to create a protection device which constitutes effective protection, without limiting the flexion angle, and which can also retain its functional ability under high radial and axial stresses,
même s'il est manié sans précaution. even if handled without care.
Selon l'invention: a) un cône de raccord, maintenu contre la pièce de liaison, de l'entonnoir de protection est enserré par un anneau de soutien According to the invention: a) a connection cone, held against the connecting piece, of the protective funnel is enclosed by a support ring

ment en forma d'entonnoir, b) l'anneau de soutien et l'élargissement en forme d'entonnoir de la pièce de liaison se recouvrent partiellement, c) un bourrelet dirigé radialement vers l'intérieur est disposé sur funnel-shaped, b) the support ring and the funnel-shaped enlargement of the connecting piece partially overlap, c) a bead directed radially inwards is placed on
le plus grand diamètre de la partie conique de l'anneau de sou- the largest diameter of the conical part of the support ring
tien, d) le bourrelet, pour pouvoir s'insérer dans un pli du soufflet, comporte un cône d'insertion, e) le côté tourné vers la pièce de liaison du bourrelet a la forme yours, d) the bead, to be able to fit into a fold of the bellows, has an insertion cone, e) the side facing the connecting part of the bead has the shape
d'un crochet à peu près dirigé radialement vers l'intérieur. of a hook roughly directed radially inward.
Le dispositif selon l'invention a l'avantage que l'anneau de soutien se laisse monter sans l'aide d'outils. Du fait que l'anneau de soutien et l'élargissement en forme d'entonnoir de The device according to the invention has the advantage that the support ring can be mounted without using tools. Because the support ring and the funnel-shaped widening of

De cette façon, on ne risque pas d'endommager le dispositif de protection, même en cas de maniement yours is capable of absorbing high radial forces. Under axial forces, the support ring can yield elastically towards the protection tube. In this way, there is no risk of damaging the protective device, even when handled

Sur la pièce de liaison 9 est tenue en même temps la bague d'appui 8 qui est montée rotative dans une rainure annulaire 11 ménagée dans la tige de la fourche d'articulation 10 (représentée schématiquement et en partie seulement), Pour son montage sur le dispositif de protection, on enfile l'anneau de soutien 6 depuis le tubl de protection sur bellows-shaped cover, for articulated shafts, comprising a protective funnel 1 fitted on the connecting piece 9 by a connection cone 12. On the connecting piece 9 is held at the same time the support ring 8 which is mounted rotatable in an annular groove 11 formed in the rod of the articulation fork 10 (shown diagrammatically and only in part), For its mounting on the protection device, the support ring 6 is threaded from the protection tubl on

Du fait que le bourrelet 4, dirigé radialement vers l'intérieur, de l'anneau de soutien 6 comporte dans le sens de ce mouvement un cône d'entrée 3, l'anneau 6 peut être mis en place de façon simple et sans qu'il soit besoin d'outils. Pour que l'anneau 6 soit mieux Because the bead 4, directed radially inwards, of the support ring 6 comprises in the direction of this movement an inlet cone 3, the ring 6 can be put in place in a simple manner and without 'it needs tools. So that the ring 6 is better
